[BUG] Missing Monitor Info and Latest Viewer Logs in System Info page

[KGL10MH]

Description

On the 'System Info' Website I don't see neither the 'Monitor Info' or the 'Latest Viewer Logs'.
With this system configuration/hardware I experience this now exactly 3 times for 3 different devices.

Steps to Reproduce

Steps to reproduce the behavior:

1. Go to "http://<Anthias IP>/system-info"
2. Not See " 'Monitor Info' & 'Latest Viewer Logs' "

Expected Behavior

I want to see the 'Monitor Info' and 'Latest Viewer Logs' on the "System Info" website.

Environment

• Device: Raspberry Pi 4 Model B Rev 1.5 (4GB RAM) & ArgonOne V2 (Daughterboard)
  https://argon40.com/products/argon-one-v2-case-for-raspberry-pi-4?srsltid=AfmBOopNCTaxxFWUhPutvYE0GV-S-VfWycpZrChfHodxynjgO0iq9B4I
• SD Card (64GB)
• OS: Raspbian GNU/Linux 12 (bookworm)
• Anthias Version: master@8c5e86b
• Installation Method: Manual Installation:

1. Raspberry Pi Image
2. Setting up over GUI, then command line raspi-config (disabled Bluetooth and WIFI)
3. Installing the ArgonOne Script 'curl https://download-argon40.com/argon1.sh | bash'
4. Install Anthias via 'sudo bash <(curl -sL https://install-anthias.srly.io/)'
5. Configure Anthias via Anthias website (noticing first time the 'System Info' not providing all the information)
6. Updating via the Anthias update sh-SCRIPT as depicted via the website instruction for updating.
7. Changed the 'hostname'.
8. Via sudo crontab -e (set a daily reboot at 06:00)
9. I couldn't set via raspi-config the display resolution and changed it then after checking 'kmsprint' then via adding in the cmdline.txt 'video=HDMI-A-1:1920x1080M@30D video=HDMI-A-2:1920x1080M@30D'
10. Many updates to the 'master' and 'lastest' the same problem persistet
11. Tried to change to 'production' (couldn't) noticed then that the production is 5 years old and saw then that it's still on the 'master' branch. ==> Reupdated again for the master to make sure.
12. Problem still persists.

@KGL10MH, thank you for providing the details.

The Latest Viewer Logs was removed (#2059) because it's not showing anything for a while. This feature can be brought back but it will be trickier since services are inside Docker containers. In theory, there are ways to bring back viewer logs:

1. Make use of shared volumes. Almost all parts of the viewer service is written in Python. It can be configured to throw logs into a log-file, which can be shared across container. One caveat with this approach is that the log file can get extremely large. Older logs need to be cleaned up.
2. Have the container that runs the back-end server call a script that runs inside the host OS. That host script calls Docker so that the logs (i.e., from the viewer service) can be obtained and passed back to the server container.

The Monitor Info field was removed (#2024) from the System Info page because its value depends on the output of the tvservice command, which was dropped in Bookworm.

@nicomiguelino

Thank you as well for the detailed info.

Was my pleasure.

I wanted the 'Latest Viewer Logs' only for what is currently playing, or if the playlist was stuck.
If I can get this in a different way, I'd be happy.
(edit)For me I would need only 48 hours back, some may need more.(/edit)

Since 'tvservice' is deprecicated, I would like it to be replaced by getting the info from 'kmsprint' and shown here. Since most of all remote in, this value is too critical!
